This work is mainly to ensure the reliability of low power low noise amplifier design and analysis which is useful for 4G receiver front ends in particularly WIMAX applications. The low noise amplifiers implemented by using different topologies namely (a) Cascoded Common source amplifier technique(b) Folded Cascode amplifier technique (c) Shunt feedback amplifier technique (d) Current reuse Com...

Design and operation of high-gain (>1000), low-power (< 75 jtW), ultra low-noise amplifier arrays are presented. The amplifier array is operated in self-biased mode, such that all amplifiers are biased irrespective of threshold mismatches, and operate with low reset noise. The amplifiers are designed for possible incorporation as pixels of hybrid solid-state photon-counting sensor. The cell pit...

Deep-brain stimulation (DBS) is an emerging research topic aiming to improve the quality of life patients with brain diseases, and a great deal effort has been focused on development implantable devices. This paper presents low-noise amplifier (LNA) for acquisition biopotentials DBS. electronic module was designed in low-voltage/low-power CMOS process, targeting applications. The measurement re...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

We report test results for a single pixel antenna-coupled bolometric detector. Our device consists of a dual slot microstrip antenna coupled to an Al/Ti/Au voltage-biased transition edge superconducting bolometer (TES). The coupling architecture involves propagating the signal along superconducting microstrip lines and terminating the lines at a normal metal resistor colocated with a TES on a t...
